Members of the Perovo Speleo caving team from Moscow, Petr Lyubimov and Pavel Demidov, are captured in motion walking along a narrow path of hard calcite crystal in a passage called Onyx Bridge. At approximately -2100m underground, this beautiful gallery lies close to the lowest camp in Veryovkina [cave].
A week later, during the flood pulse that suddenly plummeted into these chambers, all of these formations in the galleries were completely submerged.
